Question

今天我正在编写脚本，当我想测试它时，我可以看到它无法正常显示值[object Object]而不是实际值（它也没有更改值）。它显示：Click here for see the picture 它必须点击谷歌或雅虎附近的“编辑”。当我点击Google附近的“编辑”并在点击编辑时编辑它时，我想显示正确的值。我试图为Checker [Name]更改Checked [Item]的值，但它只显示undefined。

Answer 1

为Checker个对象的每个属性添加另一个输入标记。

<input type="text" id="edit-name">
<input type="text" id="edit-url">

并分别设置每个输入

var el = document.getElementById('edit-name');
el.value = Checker[item].name;
var el2 = document.getElementById('edit-url');
el2.value = Checker[item].url;

工作代码：

var Checker = [{
    name: "Google",
    url: "google.es",
  },
  {
    name: "Yahoo",
    url: "yahoo.com",
  }
]

document.getElementById('edit').style.display = 'none';

function start() {
  var SSL = new function() {
    //List urls to check
    this.el = document.getElementById('urls');
    this.Count = function(data) {
      var el = document.getElementById('counter');
      var name = 'url';

      if (data) {
        if (data > 1) {
          name = 'urls';
        }
        el.innerHTML = 'There are:' + ' ' + data + ' ' + name;
      } else {
        el.innerHTML = 'No ' + name;
      }
    };
    //Buttons configuration
    this.FetchAll = function() {
      var data = '';

      if (Checker.length > 0) {
        for (i = 0; i < Checker.length; i++) {
          data += '<tr>';
          data += '<td><a href="http://' + Checker[i].url + '">' + Checker[i].name + '</a></td>';
          data += '<td><button onclick="SSL.Edit(' + i + ')">Edit</button></td>';
          data += '<td><button onclick="SSL.Delete(' + i + ')">Delete</button></td>';
          data += '</tr>';

        }
      }

      this.Count(Checker.length);
      return this.el.innerHTML = data;
    };
    //Add name
    this.Add = function() {
      el = document.getElementById('add-name');
      el1 = document.getElementById('add-link')
      var url = el.value;
      var url1 = el1.value;
      if (url) {
        if (url) Checker.push({
          "name": url,
          "url": url1

        el.value = '';

      }
    }

    //Edit
    this.Edit = function(item) {
      var el = document.getElementById('edit-name');
      el.value = Checker[item].name;
      var el2 = document.getElementById('edit-url');
      el2.value = Checker[item].url;
      document.getElementById('edit').style.display = 'block';
      self = this;

      document.getElementById('saveEdit').onsubmit = function() {
        var url = el2.value;
        var name = el.value;
        if (url && name) {
          Checker[item].name = name;
          Checker[item].url = url;
          self.FetchAll();

    //Delete
    this.Delete = function(item) {
      Checker.splice(item, 1);

Answer 2

您使用[object Object]获得了正确的输出，因为Object.toString()完全返回[object Object]。

要以自定义格式表示您的对象，您可以将执行SSL.Edit()的{{1}}方法的部分更改为

el.value = Checker[item]
el.value = Checker[item].name; // To show the name
el.value = Checker[item].url; // To show the url

不要显示正确的值JAVASCRIPT ARRAY
